This is a small class to export quickly CSV files.
Let's see a basic example:
$header = array(
'Name',
'Age'
);
$line = array(
'Louis',
'27'
);
$csv = new SimpleCsv();
$csv->writeLine($header);
$csv->writeLine($line);
$csv->show('thats-me'); // download the file
$csv->save('/tmp/thats-me.csv') // store the file
